Stefanos Tsitsipas accused a US Open chair umpire of having a bias against him during a tirade in which he told the official, "You're all weirdos!"

Tsitsipas told Damien Dumusois that the cause of his bias was "because you're French probably and you're all weirdos!"

Top-seeded Stefanos Tsitsipas of Greece will face Australian teenager Alex de Minaur in the championship match of the Next Gen Finals on Saturday.

Both players had only dropped a set apiece in their first three matches at the tournament but each needed five sets to win their respective semifinals on Friday.

Alexander Zverev and Grigor Dimitrov both recovered from slow starts to book their places in the third round of the Monte Carlo Masters on Tuesday.

Third seed Zverev was a set down against Giles Muller before recovering strongly in the second and third sets for a 4-6, 6-3, 6-2 victory.

Grigor Dimitrov won a very nervous match against Andrey Rublev and qualified for the 1/8-finals of the Australian Open Tennis Championship. Last year's semi-finalist of the Grand Slam Grand Prix won against the 20-year-old Russian with 6:3, 4:6, 6:4, 6:4 and took a special revenge for the second round of the US Open last season.

Bulgaria's best tennis player Grigor Dimitrov, will be on the court tomorrow at about 6:00 am Bulgarian time for his third round match of the Australian Open against Russian Andrey Rublev. The match is the third in Rod laver Arena, with matches between Luksika Kumkhum  (Thailand) - Petra Martic (Croatia) and Martha Kostyuk (Ukraine) - Elina Svitolina (Ukraine).

World number two Roger Federer has eased past fellow 33-year old, the Finn Jarkko Nieminen, with a dominant display to reach the quarterfinals of the TEB BNP Paribas Istanbul Open.

Federer, showing flashes of brilliance mixed with occasional errors, closed out in just over an hour to win the second round match 6-2, 7-5.
